[z3-five] propagating form/formlib fixes

[yuppie]

Hi!


Zope 2.9.5 will ship with some form and formlib fixes backported from 
Zope 3.3. I'd like to make sure the related code in Five 1.4 and 1.5 is 
up to date.

A few questions:

- Is it fine to limit this to Five 1.4 and 1.5? I don't think many 
people use zope.app.form with older Five versions, formlib support is 
anyway new in Five 1.4.

- Is it fine to make Zope 2.9.5 required for the next Five 1.4 release?

- Five ships with its own version of pageform.pt and subpageform.pt. 
AFAICS that's only necessary in Five 1.4 for pageform.pt because the 
original version uses metal:extend-macro and metal:define-macro in the 
same tag. I propose to sync Five 1.4's pageform.pt as far as possible 
with Zope 3.2.2 and to remove all other copies of pageform.pt and 
subpageform.pt. ZopeTwoPageTemplateFiles can be created directly from 
the zope.formlib versions.


Any comments?


Cheers,
